NABU Doom

Drive A : User 1 • by DJ Sures

Created 2026-05-03 • Updated 2026-05-04

A genuinely playable 3D Doom port for the NABU complete with music, enemies, weapons, and multiple levels of demon-blasting fun.

NADOOM.COM program is located on the A: drive in user area 1. To run this, look in the Internet Adapter or Headless menu and select Cloud CPM. After CPM loads and you are presented with a A:0> prompt, type the drive (A:), and then type the user area (user 1). If you type DIR, look for the COM file (NADOOM.COM). Enter that filename at the prompt to execute the NABU Doom.

I built the original engine a year or so ago, which eventually became the foundation for creating a DOOM on the NABU PC. Before VCF Montreal, I wanted to showcase something super new and impressive with the NABU PC, so I created this. Eventually it’ll get more levels and health, etc... But right now it’s very playable and very fun!
